The Uzbek occupation of Herat in 1506-7 under Muhammad Shaybani inaugurated a period of instability in Khurasan. Herat did not, however, lose its pre-eminence in the arts of the book, but the principal Herati painters gradually dispersed towards Tashkent, Bukhara and Tabriz. Much Bukhara painting of the mid-sixteenth century is in the style of Bihzad school, albeit with simplification of architectural detail, a narrower range of brilliant colours and, ultimately, figure painting lacking in realism and vivacity. The Safavids occupied Tabriz in 1501 and their leader Ismail had himself crowned Shah of Iran. Their art was inspired by nationalistic sentiments as well as Turcoman painters of the Akkoyunlu studio. The successor of Ismail, Shah Tahmasp worked on a great illuminated Khamsa of Nizami, written by calligrapher Shah Mahmud al-Naysaburi. The other fine manuscript, Shahname, had dispersed after it was presented to the Ottoman Sultan Selim II in 1567. The depicted illustrations are from Khamsa of Nizami.
